Application filed June 10, 1807. Serial-Io. 878,281.

To all wkmndt may concern:

Be it known that I, Josnm O. Cons, a oitizen'of the United States, residing at Washington,- in the District of (Lolumhia, have invented certain new and useful Improvements in Loading Apparatus, of which the following is a s ecification. I

This inventionre ates to loadingapparw the in general and more particularly to an improved machine forloadin earth, avel' rovide alight portable hoisting machine to he so manipulated that it can be loaded by wheel. scrapers or three horse slide scra rs working abreast and kept near where 4; ese scrapers. take the earth and when loaded :to be constructed imsuch a manner that when is dumped Wlll automatically form itself into a chute which can 'be dumped into a wagon or other suitable conveyance. Said a paratus is so constructed that no part 0 the earth thereon is permitted to fall wide of the a hindrance to the continuous operation of the machine and loss of time. A further object of the invention is to m such a manner from more than one ointl that there can be no swing, or so litt to the latform that there will be no inaccuracy to t e discharge of earth from said platform. A further object of the invention is to rovide an apparatus which by reason of its ightness can e gotten into places where a steam shovel can not be taken withoutgreat A further object of the invention to rovide an apparatus which can be manufhctured and sold far below the cost of a steam shovel.

Another feature of the invention is in the fact that the platform does not offer a an u war swing of theouter portions of the plat orm prior to the 'full-loadbeing lifted, this brings a less sudden strain on said elevating mechanism. p

In order that my invention may be more thoroughly understood I have clearly illustrated oneform thereof in the accompany Fig. 4. is :a view of the platform as seen the opposite side of 1.

In the several views like numerals of reference designate similar parts of my improved apparatus.

In the drawings,- 1 designates a metal frame made referably of channel iron, 2 .a

flooring party covering said frame, and 3 wheels on which the frame is mounted for ready transportation.

4 designates an ordinary hoisting engine,

having a double drum 5, mounted on said frame, over whichdouble drum the hoisting ro es are wound.

ounted on the frame 1 are parallel cranes 1 6, 6 having braces 7, 7 and journaled on the shaft 8 in the extreme up or ends of the cranes are 'ulleys 9, 9. Pu eys 10,. 10 journaled on shaft 11, andpulleys 12, 12 journaled on shaft 13 are mounted in the cranes on which the hoisting cables are designed to travel The elevating platform 14 in the form shown is composed .of a central section 15, two side sections 16, 16 hinged to the central section as shown at 17, 17, said side sections having u turned rigid .portions 18, '18 having :rolled e ges as at 19 for the purpose of strengthening them longitudinally.

Staples 220 secured to the hinged sections 16 of the platform form attaching means for portions 21 .of the-elevating chains 22 above the latform, while chains 23 of proper lengt are secured to said staples 20 beneath i the platform to control the amount of the collapse of the platform and consequently the width of the floor of the contents of said platform. 4

. In operation the platform 14 is lowered to rest fiat on the ground as shown in dotted lines Fig. 2,the elevating chains are helda little'to one side while several scraper loads of earth are dumped on the platform, the hoisting engine then starts to elevate the platform, at first bringing the parts 1611p to the position shown, then the whole platform is lifted,this gradual taking up of the whole weight is les's shock to the elevatingparts.

, After the platform is elevated to the proper height "one hoisting chain'or the other as pre- ,ferred is stopped, while the other continues,

which tilts t e'platform anddischarges the earth into any suitable receptacle or coniihe' shift of the Work of the scrapers is followed by the loader, thus avoiding a long haul for the scrapers, which is very egrpensive.- I

'I am aware of patents on dumplng and elevatirig latforms but they arenotpracticalfor t; e following reasons: If the plat formis-mad'e wide enough to drive the largest Wheel or three horse slide scrapers working abreast thereon, said platform will not depositallof said earth into a wagon but my improved platformis so constructed as to "form a chute that canbe regulated to disprovement'. V What I claim and desire to secureby Letters Patent is:

char e all ofits contents properly, and it is for t is feature I-claim 1. A hoisting platform, comprising a solid central section e on at each end, side secplatform longitudina tions connected t ereto, and means for raisthe platform bodiiy and then tilting said whereby the con' tents thereof is discharged through one of form, composed of a materia said 0 en ends.

, 2. loading apparatus, comp ising a plat-- portion open ateach-end, side sections for the material-containing portion and su'bse-.

retainin the material on the platform mov-' able-wit respect to the material-containing orjtion, and means for hoisting said plat; orm, including connections to said sections for first moving the same withres'pect to q uently raising the-platform bodily and "then I tilting said p'latform longitudinally, whereb.

thecontents thereof is discharged throng one-ofsaid open ends.

3. AJOadmg appara y l 8? P form, composed foffa matelial containmg 'portiono 4 v taining t e material onthe platform movahle with respect to the materiatcontaining en at each end, side sections for re.-

-11. The combination with a collapsiblev Y apparatus, som

hoisting devices connected to the side sec-'- tionsvand central portion. for first moving the tral portion and then bod y raising the chute'and then tilting said platform longitudinally, whereb the contents thereof is discharged throug one ofsaid open ends;

5. 'A collapsible hoisting platform comprising a plurality of sections hinged toside sections'radially with res ct to the cengether, the sections at op osite sides-of said platform havin upturne portions.

(ii A collapsi 1e hoisting platform, comprising a plurality of sections hinged together, thesections-at o posite sides of saidplatform being upturned, the edges .of said upturned sections being rolled. y

7-.- A normally flat hoisting platform, comprising a solid central section open at each end, side sections pivotally'connected thereto, a and means connected to'said side sections for collapsing the same towards each other and limiting such movement to form a chute.

8. Anormally flat hoisting platform, comprising a solid central sectioniopen at each end, side sections pivoted thereto, means extending between said side sections and connected to a hoistin device for collapsing, and means'for limiting the inward travel of said sections to form a chute and a hoisting so s device for bodily lifting said chute and then I tilting the same longitudinally, whereby the contents thereof is discharged through one of saido en ends. I I,

' 9. collapsible hoisting platform CD111: prising a plurality of separate sections hinged together, and a flexible band secured at its ends to the outside sections of said latfonn and extending transversely across t e intermediate sections thereof, whereby the swinging movement of said hinged sections is lim- I ited. Y

1( A collapsible hoisting platform, comprising a plurality of sections hinged togeth'er, a, flexible strapextending across the ends secured to the outside sections 0 .the platform, and 'a plurality of flexible stra s extending transversely across the per side" of said platform, each of said straps eing secured at their ends to the outside sectionsof under side of said platform transversely of the hinged sections thereof, and havin its v hoisting platform, having open ends adapted l to form a chute when raised, of means for l successively said platform bodily and 7 tilting sai platforni -longitudinally, to discharge the contents thereof through one of said open ends.

, l2. The combinationlwith a collapsible "ho1stmgplatform,having 0 en ends adapted to form Ya. chute when l h v ed, of hoisting. mechanism having a pair of cranes and hoisting cables assing over said cranes, 'seid hoisting cab es being attached to said platform adjacent to the opposite. ends thereof for bodily lifting the same, and for tilting 5 said' chutelongitudinelly, whereby the contents thereof is discharged through one of said open ends. g

In testimony whereofl afiix signature in presence of two witnesses.
